A commuter went to his parked car and was shocked to find a suspected illegal immigrant asleep in the back seat.

The 51-year-old building site worker opened the door of his MG at 5am to be confronted by the sight of the dishevelled man.

The cheeky dosser had even taken off his trainers to get comfortable.

A video clip of the incident, recorded with a camera phone on a side street in Basildon, Essex, on Friday, shows the mystery man claiming that he had used “keys” to open the car door.

Caught: Immigrant in a car

When asked why he was in there, he claimed he was tired. He said he was ­staying nearby with his sister.

The man wore a tracksuit top and spoke in poor English with what sounded like an Eastern European accent. Soon after being rumbled he scurried away.

The unnamed motorist, who was about to drive to Croydon, South London, told the Sunday People: “It was unbelievable. I’ve no idea how he got in there. I’ve got five alarms.

Snapped: After he got out of the car

“God knows what he was up to. He could well have been an illegal immigrant. I’ve no idea where he came from or how he got in my car.”

Migrants have been turning up in ­unusual places as the Calais crisis worsens. One suspected illegal from Sudan was found hiding under a horsebox at the Royal International Horse Show at Hickstead, West Sussex, last week.

Another turned up in a furniture van at a university in Canterbury, Kent.

Authorities have not been notified about the man in the back of the car.
